适用于中药、食品、化工、轻工等行业的水或有机溶媒溶液（比如乙醇）等的蒸发浓缩。尤其适合多品种、多批次、低粘度溶液的浓缩。

Suitable for the evaporation and concentration of water or organic solvent solution (eg. ethanol) in the industries of traditional Chinese medicine, food, chemical industry and light industry. It is especially suitable for the concentra-tion of multi - variety, multi - batch and low viscosity solution.

07 08

料液是从蒸发器顶部加入，在重力作用下沿管壁呈膜状流下，在此过程中溶剂不断地被蒸发而使溶质增浓，在换热器底部得到其浓缩液。

降膜式蒸发器可以蒸发浓度较高的溶液，对粘度较大的物料也适用。但是液膜厚度在换热管内的分布不易均匀，其传热系数较升膜蒸发器小一些。

Main characteristics: material liquid is feeding from the top of evaporator; under the action of gravity, it flows down along the wall of the pipe. In this process, the solvent is continuously evaporated and the solute is thickened, and the concentrate is obtained at the bottom of the heat exchanger.

The falling film evaporator can vaporize the solution with higher concentra-tion, and it is also suitable for the material with larger viscosity. But the thickness of the liquid film is not easy to be evenly distributed in the heat transfer tube, and the heat transfer coefficient is smaller than that of the rising film evapora-tor.

工作流程 Main Process

较短的预加热时间，生蒸汽与产品冷凝水无任何交叉接触。

蒸发温度低，可控制在45-55℃，不发泡、不跑料、蒸发效率高。

产品浓缩倍数高，收膏量可到450-600kg（以5T蒸发系统为例），高浓度、高粘度的物料可配备刮板薄膜浓缩器。产品在蒸发器内有更短停留时间，根据产量需要，停留时间可以降低至6-10分钟。

全自动CIP清洗，缩短CIP清洗时间和清洗液耗量，设备做工精密，做到无残留、无死角。

Lower evaporation temperature; the lowest evaporation temperature can be controlled at 45-55 deg C, no foaming, no running material, high evaporation efficiency.

There is no cross contact between the fresh steam and the condensate at the shortest preheating time.

Final product with higher concentration and less quantity. Eg. 5ton/h evapo-ration system can get 450kg~600kg final product. If higher concentration and viscosity product required, scraper thin film evaporator can be adopted.The shorter residence time of the product in the evaporator, the minimum residence time can be reduced to 6-10 minutes according to the production needs.

Automatic CIP cleaning, shorten CIP cleaning time and cleaning liquid consumption, equipment precision, complete without residue, no dead angle.
